When to publish (ISO timestamp, must be in the future)
Stamps approval on the post so it publishes at its slot. CAUTION: approving a post whose slot already passed publishes it IMMEDIATELY (the missed-slot recovery); publishedImmediately says when that happened.
Publishes to the connected channel. A review-mode post must be approved first (409 APPROVAL_REQUIRED). Instagram/Facebook/LinkedIn/X return the result inline; TikTok/YouTube/Pinterest return 202 with a job to poll. success:false responses carry a plain-language error and whether retrying can help.
